An 82-year-old Hanover man was assaulted and robbed in Codorus State Park on Aug. 29, according to Codorus State Park Chief Ranger William Hornberger.

At about 4:15 p.m., somebody hit the man, who was in the marina area of the park, on the back of the head and stole his wallet, keys and car, Hornberger said.

The two suspects were men in their 20s with thin builds. They arrived in a dark-colored sedan with Maryland tags and were walking a pit bull.

They drove off in the man's gray 2004 Chevy Malibu with license plate number JCM9314, Hornberger said.

Anyone with information is asked to call Codorus State Park rangers at 717-637-2816.

Visitors at the southwestern York County park Friday said they couldn't fathom a crime like this happening in what they described as a serene area.

"We never had an inkling that something like that would happen here," said Linda Stoner, of Lancaster County, who was visiting the park with her husband. "We think we are protected because people are always around."
